This paper describes the migration of a monolithic RBAC authorization system to a centralized microservice architecture, highlighting the process and benefits of modular, scalable authorization management.

Contribution

It presents a detailed methodology for transitioning from a monolithic RBAC system to a centralized microservice authorization architecture.

Findings

Successful implementation of microservice authorization microservice

Enhanced scalability and flexibility in authorization management

Streamlined transition process from RBAC to microservice architecture

Abstract

Monolithic applications used to be considered the standard for software development. However, due to the rapid evolution of technology and the increasing demand for scalability and flexibility, these applications have become increasingly inadequate for contemporary environment. In response to these challenges, developers have begun to adopt a microservice (MS) architecture, which offers a modular approach to software creation. However, this transition requires to rethink the enablement system to meet the new requirements. Two MS architectures can be deployed: a centralized or decentralized architecture. Based on the requirements of the application's users, a centralized authorization management architecture was chosen. The purpose of this study is to explain the migration from a Role- Based Access Control (RBAC) authorization system to a centralized microservice authorization architecture. The migration is carried out in two stages: 1) Creation of an authorization microservice 2) Abandonment of RBAC
